Esperion Moving Ahead with Bempedoic Acid Trials
Esperion Therapeutics says it plans to start global pivotal Phase 3 efficacy and safety studies of its bempedoic acid for lowering low density lipoprotein cholesterol (LDL-C) in the fourth quarter of this year, along with a global cardiovascular outcomes trial in patients with elevated LDL-C levels who are unable to tolerate statins.
The company says that in conversations with FDA it reached alignment on the definition of statin intolerance, key design features of the cardiovascular outcomes trial, and the regulatory approval pathway for a cardiovascular disease risk reduction indication in statin intolerant patients. However, it says, FDA did not provide clarity on a regulatory pathway for an LDL-C lowering indication in statin intolerant patients.
“The agency indicated its position regarding an LDL-C lowering indication could be impacted by potential future changes in their view of LDL-C lowering as a surrogate endpoint or the possibility of a shift in the future standard of care for statin intolerant patients with elevated LDL-C levels,” Esperion says. “In the event LDL-C lowering is no longer a surrogate endpoint for initial approval in the future, Esperion would plan to submit a NDA to FDA for a cardiovascular disease risk reduction indication on the basis of a successful completion of the cardiovascular outcomes trial, which would include the results of the LDL-C lowering efficacy studies, by 2022.”
